Morphology

semilunar = lunar (transparent) = semi + lunar

The meaning is directly compositional: 'semi-' means half and 'lunar' means moon-related, yielding 'half-moon shaped'.

Etymology

Semilunar comes from semi- ('half') and lunar ('moon'), so it literally means 'half-moon'. Think of a semicircle or the thin crescent you see in the sky, and you will remember that semilunar describes something shaped like a small crescent or half-moon.
